本文针对浅层稠油油藏热采目前生产井网、井距形式及井网密度现状,利用密闭取心、生产动态分析、驱替特征、累积产量特征[f(nt)法]、油藏热平衡、数值模拟及国外稠油热采井网密度类比等研究方法,对优化合理井距、极限井距及经济合理生产井数进行了系统分析,指出了浅层稠油油藏热采目前的井网尚需进行加密,才能真正有效动用油藏,进而改善蒸汽吞吐和蒸汽驱的开发效果。这对于浅层稠油油藏热采增加可采储量、提高采收率将具有重要意义,是今后若干年稠油稳产上产的重要途径。
In this paper, according to the current production well patterns, well spacing patterns and well pattern densities in the thermal recovery of shallow heavy oil reservoirs, this paper uses closed coring, dynamic production analysis, displacement characteristics and cumulative yield characteristics [f (nt) method] Thermal equilibrium, numerical simulation and well density analogy of heavy oil thermal recovery in foreign countries, systematically analyzed the optimal reasonable well spacing, well spacing and economically rational production well numbers, and pointed out that the current thermal recovery of shallow heavy oil reservoirs Well network still need to be encrypted in order to truly effective use of reservoirs, and thus improve the steam huff and steam drive development. This will be of great significance for the thermal recovery of shallow heavy oil reservoirs to increase recoverable reserves and increase oil recovery, which is an important way for the stable production of heavy oil in the coming years.
